目的:比较采用经阴道彩色多普勒超声(TVCDS)与经腹彩色多普勒超声(TACDS)对早期异位妊娠诊断准确率的差异,为妇科疑似早期异位妊娠患者选择不同的超声诊断方式提供临床依据。方法:回顾性分析2012年1月~2013年6月该院术前行TACDS和TVCDS检查并经术后病理证实为早期异位妊娠的155例患者,比较两种检查方式诊断准确率的差异及相关超声影像学表现检出率的差异。结果:TACDS诊断早期异位妊娠的准确率为76.77%,TVCDS诊断准确率为92.90%,两种检查方式诊断准确率比较差异具有统计学意义(P<0.05)。同时,在附件区团块、盆腔积液、子宫内假孕囊、胚芽反射、原始心血管搏跳等早期异位妊娠典型超声影像学表现的检出率方面,TVCDS均优于TACDS,差异具有统计学意义(P<0.05)。结论:TVCDS诊断早期异位妊娠的准确率显著高于TACDS。该检查方式可极大地改善异位妊娠的早期诊断,并为后续治疗提供更多、更有价值的临床资料。
OBJECTIVE: To compare the diagnostic accuracy of transvaginal color Doppler ultrasound (TCDS) and transvaginal color Doppler ultrasound (TACDS) in early ectopic pregnancy and to select different methods of ultrasound diagnosis for patients with suspected early ectopic pregnancy Provide a clinical basis. Methods: A retrospective analysis of 155 patients with early ectopic pregnancy confirmed by TACDS and TVCDS before operation from January 2012 to June 2013 was performed. The diagnostic accuracy of the two methods were compared. Correlation of ultrasound imaging detection rate of the difference. Results: The diagnostic accuracy of TACDS for early ectopic pregnancy was 76.77%, and the diagnostic accuracy of TVCDS was 92.90%. There was significant difference between the two diagnostic methods in diagnostic accuracy (P <0.05). At the same time, TVCDS were superior to TACDS in the detection rate of typical ultrasonographic findings of early ectopic pregnancy such as pelvis, pelvic effusion, intrauterine pseudobubbles, germ-reflex, and primary cardiovascular beating in the appendix, Statistical significance (P <0.05). Conclusion: The accuracy of TVCDS in diagnosing early ectopic pregnancy is significantly higher than that of TACDS. This test method can greatly improve the early diagnosis of ectopic pregnancy, and provide more and more valuable clinical data for follow-up treatment.
